Abstract
A method for manufacturing a light emitting device includes disposing on lateral surfaces of the light emitting element, a first wavelength converting member containing a first phosphor to convert the first light emitted from the light emitting element into a second light having a second peak wavelength longer than the first peak wavelength. The light emitting element provided with the first wavelength converting member is disposed on a base. A second wavelength converting member is disposed on the base. The second wavelength converting member covers an upper surface of the light emitting element provided with the first wavelength converting member and lateral surfaces of the first wavelength converting member provided opposite to additional lateral surfaces of the first wavelength converting member. The additional lateral surfaces face the lateral surface of the light emitting element. The second wavelength converting member contains a second phosphor.
